Bill Murray and his close friend, rocker Jenny Lewis, were together again last week when Murray and cast mates from his “Very Murray Christmas” partied at the Carlyle following the Netflix special’s premiere.

Lewis revealed at the screening how the May-December friends first met.

“I met him at Austin City Limits. I was playing the festival, years ago, and I was covering a song called ‘Love Hurts’. . . and I looked over in the middle of the set and saw him at the side of the stage,” she said.

That night, “my band and I, we took him back to our tour bus, and he asked me for a bottle of water and a beer, and he took off his hat, and poured the bottle of water in his hat, and then put his hat on. And that’s when I knew we were going to be friends for a long time.”

She said she’s still unsure why he dumped the water on his head. Lewis and Murray stayed close, singing along as David Johansen performed.
